DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example 1

[0022] As attached Figures 1 to 4 A cooling oil tank for a Roots blower mechanical seal is shown, comprising an outer shell 1, which is made of aluminum alloy and stainless steel. This material not only has excellent mechanical strength and can protect internal components from physical damage, but also has excellent corrosion resistance and can effectively cope with various harsh environments and corrosive media. An oil inlet 2 is provided on one side of the outer shell 1, and a cooling oil tank 4 is connected below the oil inlet 2. An oil outlet 5 is provided below the cooling oil tank 4. The cooling oil tank 4 is made of stainless steel to ensure the stability of the structure and long-term corrosion resistance. The capacity design of the cooling oil tank 4 needs to meet the needs of continuous long-term operation, and sufficient space is reserved to avoid overflow when the oil expands. The size of the cooling oil tank 4 should be calculated based on the total oil volume of the system and its thermal expansion coefficient. The oil inlet 2 is designed above the cooling oil tank 4, and the fluidity and gravity of the oil are used to facilitate the natural inflow of the oil. The oil outlet 5 is designed at the bottom of the cooling oil tank 4, and the gravity of the oil is used to achieve self-flowing discharge, thereby simplifying the process of emptying the cooling oil tank 4.

[0023] A coolant interface 3 is provided on one side of the oil inlet 2, and a heat-conducting layer 6 is provided on one side of the cooling oil tank 4. The heat-conducting layer 6 is made of a material with high thermal conductivity, which can effectively improve the transfer efficiency of heat energy. For example, copper and aluminum are commonly used high thermal conductivity materials, and their thermal conductivities are 401 W / (m·K) and 237 W / (m·K), respectively. A coolant tank 7 is provided on one side of the heat-conducting layer 6, and the coolant tank 7 is filled with coolant through the coolant interface 3. A heat sink 8 is provided at the center of the coolant tank 7. Immersing the heat sink 8 in the coolant can significantly increase the heat dissipation area and improve the heat exchange efficiency. This direct contact method is much more effective than the traditional heat dissipation by air. The heat sink 8 is made of stainless steel or a specific alloy material, which can prevent the heat sink 8 from being corroded due to long-term exposure to the coolant, thereby ensuring the long-term stable operation of the system. A water inlet 9 is provided on one side of the heat sink 8, and a water outlet 10 is provided on one side of the water inlet 9.

[0024] A connecting mechanism 11 is provided at the center of the outer wall of the housing 1. Through the construction of the connecting mechanism 11, the device can be quickly connected and installed on the Roots blower, which is convenient for maintenance and overhaul by the staff. Example 2

[0025] Based on Example 1, the solution in Example 1 is further detailed in combination with the following specific working method. Figures 1 to 4 As shown, see the following description for details:

[0026] As a preferred embodiment, the heat conductive layer 6 makes the interior of the housing 1 a double-chamber structure, and the heat of the cooling oil tank 4 can be transferred to the coolant tank 7 through the heat conductive layer 6. Furthermore, the double-chamber design effectively isolates the heat source, reduces the risk of thermal decomposition of the oil, and extends the service life of the oil.

[0027] As a preferred embodiment, the coolant interface 3 fills the cooling oil tank 7 with fluorocarbon, which is in full contact with the heat sink 8 and the thermal conductive layer 6. Furthermore, the fluorocarbon coolant has excellent heat dissipation performance and can quickly absorb heat from the heat dissipation element. It also has excellent insulation properties and low viscosity to ensure that it flows smoothly between the heat dissipation elements. The low surface tension can ensure that the liquid fully covers the surface of the element, thereby improving the heat exchange efficiency.

[0028] As a preferred embodiment, sealing rings 12 are provided at the connections between the heat sink 8 and the water inlet 9 and the water outlet 10. The water inlet 9 allows liquid to pass through the heat sink 8 to take away heat. Furthermore, the sealing ring 12 is made of rubber material to prevent contamination caused by the liquid in the coolant tank 7 and the liquid circulation of the heat sink 8.

[0029] As a preferred embodiment, the connecting mechanism 11 includes a base 13, a screw hole 14 and a hook 15. The outer wall of the base 13 is provided with a screw hole 14. There are several groups of screw holes 14, and each group of screw holes 14 is evenly arranged along the vertical direction of the base 13. A hook 15 is provided at the center of the screw hole 14. There are two groups of hooks 15, and the two groups of hooks 15 are symmetrically arranged along the vertical direction of the base 13. Furthermore, the base 13 is made of metal material with a thickness of 10 mm, and is connected to the device through the screw hole 14. Multiple groups of screw holes 14 enable the connecting mechanism 11 to be firmly connected to the device. The hook 15 is made of stainless steel material, which plays a role in stabilizing the connection.

[0030] As a preferred embodiment, a connecting plate 16 is provided on one side of the hook 15, and the connecting plate 16 is connected to the Roots blower. The device can be fixed in the Roots blower through the connecting plate 16 and the connecting mechanism 11. Furthermore, the connecting plate 16 is made of metal material. After being firmly connected to the device by bolts, the hook 15 is quickly stuck in the opening through the opening above the connecting plate 16, so that the device is fixed in the Roots blower.

[0031] The working process of the utility model is as follows: first, the connecting plate 16 of the device is connected to the Roots blower. After completion, the oil inlet 2 of the device is connected to the place where the cooling oil is stored, so that the cooling oil tank 4 in the device is filled with cooling oil, and then the device is fixed on the Roots blower through the hook 15 of the connecting mechanism 11, and the oil outlet 5 is connected to the cooling pipe near the mechanical seal port of the Roots blower to start the cooling oil. At the same time, the water inlet 9 and the water outlet 10 on the heat sink 8 of the other chamber of the device are connected to the water body. The cooling oil is cooled and dissipated by the combined cooling in the coolant tank 7 located on one side of the cooling oil tank 4 in the double-chamber structure. The above is the working principle of the cooling oil tank for the mechanical seal of the Roots blower.

[0032] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model should be included in the protection scope of the present utility model.
